Applying argmin in natural language processing Argmin and topic modeling

Jul 19, 2024 ... OLS: im confused, shouldn't this be arg min? Because we're looking for b1 and b2 that minimize the residuals? In particular, in contrast to these argmin-theorems we do not require that the limit process has a unique minimizing point. In the non-unique case the limit- ...

The numpy.argmin() method returns indices of the min element of the array in a particular axis. Syntax : numpy.argmin(array, axis = None, out = None) argmin offers abstractions over basic Vec s, ndarray and nalgebra types. For performance reasons, the latter two should be preferred. Which one to use is a ... Returns the indices of the minimum values along an axis. a array_like axis int, optional out array, optional keepdims bool, optional ˆx = arg min x. [ky − Φxk2. 2 + λkxk0]. Wonderful result: can optimize `1 regularized least squares instead. ˆx = arg min x. [ky − Φxk2. 2 + λkxk1]. Now it's ... Oct 28, 2021 ... Is there a way to perform an argmax on a subset of a vector determined by a bitarray. This bitarray tells whether the index should be considered or not.
